TiVo is rolling out an update with a bunch of new(ish) features for TiVo HD and Series3 high definition recorders. We knew that the latest software update would enable the eSATA port, meaning you could plug in an external hard drive. But there are a few other features coming to the HD TiVos. Some of these features have been available on TiVo's standard definition boxes for a while now:

• Multi-room viewing feature that lets you watch shows recorded on one TiVo using another TiVo connected to your home network
• TiVoToGo lets you transfer recorded content from your TiVo to PC on your home network
• Progressive downloading for Amazon Unbox and TiVoCast means you can start watching downloaded videos before the download is complete

As for external storage, TiVo and Western Digital have partnered to offer a "My DVR Expander drive" for TiVO HD and Series3 users. Essentially, this is just a 500GB hard drive and enclosure that plugs into the eSATA port. It'll cost $199, but you might be able to find other eSATA hard drives that will work just as well.
